Oxo-sulfido- and oxo-selenido-molybdenum(VI) complexes possessing a dithiolene ligand related to the active sites of hydroxylases of molybdoenzymes: low temperature preparation and characterisation

Oxo-sulfido- and oxo-selenido-molybdenum(VI) complexes with an ene-1,2-dithiolate ligand are generated as models of the active sites of molybdenum hydroxylases. The sulfide and selenide groups are highly reactive toward triphenylphosphine in the order of Se > S.
